13.To re-install the cutterhead, reverse the above steps.

Note: Make sure that the fence base casting is level with the Outfeed table when securing.

Use a good grade of light grease on the steel adjusting screws located in the raising and lowering mechanisms of the work tables.

Occasionally, apply a few drops of light machine oil to the infeed/outfeed gibs. This permits the tables to slide freely.

The cutterhead ball bearings are lifetime lubricated
and need no further care.	Figure 45
